Career
He is regarded as a pioneer of Belgian tennis. From 1946 to 1947 he was president of the International Tennis Federation. De Borman was cofounder of the Royal Léopold Club in 1898.
That same year he reached the semifinal of the 1904 Wimbledon Championships in which he lost to Major Ritchie in straight sets.
Afterwards he became chairman of the tennis department at the Royal Léopold Club in Brussels. In his book "Lawn Tennis at Home and Abroad" (1903) A. Wallis Myers describes De Borman: "His style is not graceful, but he plays a strong game and is plucky in a match.
He has a difficult reverse cut service and a great forehand drive, which he takes at the top of the bound with a straight arm, which causes the ball to shoot when it touches the ground."
Since 1920 the prize for the junior championship of Belgium is called the Borman Cup. The stadium of the Royal Léopold Club, built in 1952, also carries his name.
In 1907 Paul de Borman married Anne de Selliers de Moranville who participated in the tennis event at the 1920 and 1924 Olympic Games.
Their children Geneviève (b 1908), Léopold (b 1909) and Myriam (b 1915) also became Belgian tennis champions.
